The current drawn can sometimes be quite high, especially if the switched-off state is really a standby state. Tt has long been recommended that to save on power consumption, and the cost associated with wastage of electrical power, that appliances arc switched off at the wall, where they are connected into the power supply by way of a general purpose outlet (hereinafter referred to as a power point). However, it can be inconvenient to switch power points off. Moreover, sometimes the power point is located behind heavy furniture, making it impossible, or at least impractical, to turn the power point off.
[0003] The present invention aims to provide a remote control general purpose outlet isolation switch which alleviates one or more of the problems of the prior art Other aims and advantages of the inversion may become apparent from the following description.

the relay having contacts which connect the incoming power supply to an outgoing power supply when in the off condition and disconnecting the incoming power supply from the outgoing power supply when in the on condition.
[0005] Preferably, the conditioned power supply is split between a relay power supply for supplying power to the coil of the relay and an eJectronic component power supply for supplying power to the electronic components in the remainder of the electrical circuit. In such form, the electronic component power supply provides to the radio frequency receiver and the toggling power circuit. Preferably, the toggling power circuit includes two programmable integrated (switching) circuits. Tn $uch form, it is preferred that capacitive elements arc provided in parallel the power supply to. the radio frequency receiver and the programmable integrated (switching) circuits.
[0006] The two programmable integrated (switching) circuits comprise a first PIC and a second PIC. The first PIC has an electrical connection to the radio frequency receiver for transmitting data from the radio frequency receiver to the first PIC upon receipt of a predetermined signal by the radio frequency receiver. The first PTC also has an electrical connection to the second PIC for outputting a **go code" from the first PCI to the second PTC. The second PIC has an electrical connection to a relay toggling circuit. Preferably, the relay toggling circuit includes an NPN transistor, the base of which is connected to the second PIC, the collector of which is connected through the coil of the relay and in parallel with a rectifier to the relay power supply.
[0007] In such form, the receipt of a matched radio frequency signal causes the circuitry to activate the NPN transistor, thereby connecting the relay power supply through the transistor to ground to open the circuit and put the relay into its on condition to isolate the incoming power supply from the outgoing power supply. It will be seen that circuitry ofihe present invention is designed to provide a failure mode which facilitates connection of the incoming power supply to the outgoing power supply.
